    Abstract: A fluid injection system includes a container and fluid injection device. The fluid injection device includes a housing having a flow tube having an inlet end and an outlet end. A shroud is positioned between the inlet end and the outlet end and has a first end and a second end defining a ramped surface therebetween. The shroud redefines at least a portion of the fluid pathway as a constricted fluid pathway. A diverter port is between the inlet end and the shroud and diverts a portion of the inlet fluid into the container. An injection port is between the shroud and the outlet end and receives product from the container. The first end of the shroud includes a step defining a notch in fluid communication with the diverter port. The second end defines a recess in fluid communication with the injection port.

    Abstract: A backpack sprayer system includes a mounting bracket having a battery receiving fixture to receive a battery. A first tank is mounted to the mounting bracket and holds a diluent. A second tank is mounted to the mounting bracket and holds a liquid concentrate. A mixing manifold is mounted to the mounting bracket and has a first inlet fitting to receive a fixed amount of diluent and a second inlet to receive an adjustable amount of liquid concentrate. The fixed amount of diluent and adjustable amount of concentrate are combined to form a mixed solution and the mixing manifold includes a mixed solution outlet. A positive displacement pump is mounted to the mounting bracket and a suction port coupled to the mixed solution outlet and a pressure port fluidly coupled with a spray device. A control unit is mounted on the mounting bracket and receives power from the battery.

    Abstract: A spreader having a hopper for particulate material with discharge openings over two separate different areas along the hopper bottom, a pair of wheels upon separate drive shafts mounted for rotation to a lower frame which supports the hopper, and a rear frame extending from the hopper to provide a pair of handles. Two rotatable shafts with agitator elements are mounted over each of the different hopper areas. Each of the agitator shafts are coupled for rotation by different ones of the drive shafts. Two gates with openings are disposed below the hopper each along different ones of the areas dividing the hopper bottom. Each gate is movable to close and open the openings of the hopper in the area associated with the gate. A pair of controllers are provided each coupled to a different one of the two gates to independently move the gates between open and close positions.

    Abstract: To assist the filtering from a tank into the inlet port of the pressure chamber of a sprayer, an additional pumping structure is attached to the pumping mechanism of the sprayer. A hose extends into the tank of the sprayer and draws fluid from the tank into the additional pumping structure. Fluid is pumped from the additional pumping structure via the hose to provide a jet of fluid upon a filter over the inlet port. The jet of fluid flushes the filter and retards the accumulation of debris thereon, thereby retarding the clogging of the filter.

    Abstract: A spreader includes a frame having wheels mounted on an axle. A gear assembly on the axle is coupled with a shaft. A hopper is mounted on the frame and holds particulate that empties through an opening within the bottom wall. An impeller is mounted on the shaft and receives the particulate emptied from the hopper. A controlled-release assembly is mounted about the shaft and includes a drive housing secured to the hopper. The drive housing has a funnel opening to dispense the particulate therethrough. A transfer wheel within the drive housing is rotatably coupled to the shaft. When the shaft is rotating, the transfer wheel rotates whereby the particulate is delivered to the funnel. When the shaft is stationary, the transfer wheel is stationary whereby particulate is not delivered to the funnel.

    Abstract: A sprayer system includes a diluent tank, a mounting bracket mounted to the diluent tank and a concentrate tank mounted to the mounting bracket and diluent tank. A mixing manifold is mounted to the mounting bracket and has a first inlet fitting to receive a fixed amount of diluent and a second inlet to receive a liquid concentrate. The diluent and concentrate are then combined to form a mixed solution. The mixing manifold includes an outlet. A positive displacement pump is mounted to the mounting bracket and has a suction port fluidly coupled to the mixed solution outlet. A pressure port may fluidly couple with a spray device. The second tank may be separable from the first tank and mounting bracket without requiring removal of the mixing manifold or positive displacement pump.
